Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457546, here are decompositions:

67 + 31457479 = 31457546
97 + 31457449 = 31457546
163 + 31457383 = 31457546
199 + 31457347 = 31457546
277 + 31457269 = 31457546
397 + 31457149 = 31457546
619 + 31456927 = 31457546
643 + 31456903 = 31457546

Showing the first eight; more decompositions exist.
